 We can see in verse 5, Then I acknowledged my sin to you and did not conceal my iniquity. I said, I will confess my transgressions to the Lord, and you took away the guilt of my sin. So he's talking about two different things here. We're talking about the joy of forgiveness, and we have forgiveness the moment that we come to know Jesus Christ as Lord and Savior. And we ask him to come into our life. And he sets us apart for himself. That's called sanctification.
